Backup .com to look at more than one disk

At the momment backup .COM only looks at dsk01. We would like it to look at both disk areas. BUT - we also don’t know if any other db jobs look at all of the snp, rda files too. Getting the TDMDBF com file look at dsk01 AND dsk02 for it's rda & snp files is probably quickest.

Thamks in advance.

Re: Backup .com to look at more than one disk

Hi,

>>Backup .com to look at more than one disk
Do you mean to take BACKUP of files from multiple disks from the singe BACKUP command?

In this case you can do that by using /INPUT_FILES qualifier. Here you need to specify the files name (which you want to BACKUP) from multiple disks in a file and that file needs to be specified as the input specifier in the BACKUP command.

My psychic powers are too weak to tell me
what this system is, or what "dsk01" and
"dsk02" are, or what's in your "backup .COM".

> BUT - we also don't know [..]

And you think that someone here _does_ know?

> [...] the TDMDBF com file [...]

Yet another mystery.

Re: Backup .com to look at more than one disk

Hi,

Yes, as Steven said, you query is not so clear. Please describe.
Below is the small example how you can backup the files from multiple disks.

$ dir VISHAK$DKA100:[000000]TEST.COM;1

Directory VISHAK$DKA100:[000000]

TEST.COM;1

Total of 1 file.
$ dir VISHAK$DKB200:[000000]WAIT.COM;1

Directory VISHAK$DKB200:[000000]

WAIT.COM;1

Total of 1 file.
$
$ type backup.com
VISHAK$DKA100:[000000]TEST.COM;1
VISHAK$DKB200:[000000]WAIT.COM;1
$
$
$backup/log backup.com/input_files temp.bck/save
%BACKUP-S-COPIED, copied VISHAK$DKA100:[000000]TEST.COM;1
%BACKUP-S-COPIED, copied VISHAK$DKB200:[000000]WAIT.COM;1
$
$
$backup/list temp.bck/save

Re: Backup .com to look at more than one disk

If You try it and detect the used VMS/backup version is too old (before 7.3-2 or 8.3 whenever the /INPUT qualifier was introduced),
depending on the length of the list, logical names and logical name lists can be used to achieve the desired result.

Example:
define todo disk1:[dir1...],disk2:[dir2...]
backup todo output.bck/save

But be aware if there are the same directory names on different disks: on restore they can't be directed to different disks, they will be mixed into the same disk;[dir...]: which may be wanted or not.

Re: Backup .com to look at more than one disk

Hi,

Files with .RDA and .SNP types are basically RDB files. You can use RMU to backup such files. Refer the below link on RMU reference manual.
